"Modulus" was designed as a robot with possible domestic applications, but in reality it was open to any future development. Modularity - hence its name - is one of its principal characteristics, and it has been designed for adaptation to the widest possible range of applications. The robot can carry a tray with its two arms. Its head and big eyes making it into a really human character, reliable, and a companion. A few Moddy robots were sold in Norway. Modulus by Sirius - 1984
